The fissioning of a single uranium nucleus. The fusing of a gram of deuterium.

Work Step by Step

A comparison of Tables 34.2 and 34.3 shows that the fissioning of a single uranium nucleus releases about 10 times as much energy as the fusing of a pair of deuterium nuclei. A gram of deuterium contains many times more atoms than a gram of massive uranium atoms. Thus, there is much more more energy liberated per gram in the fusion of deuterium.
